So I'm working on an exceedingly large codebase, and recently upgraded to gcc 4.3, which now triggers this warning: warning: deprecated conversion from string constant to ‘char*’ Obviously, the correct way to fix this is to find every declaration li...

I am working on Linux with the GCC compiler. When my C++ program crashes I would like it to automatically generate a stacktrace. My program is being run by many different users and it also runs on Linux, Windows and Macintosh (all versions are compiled u...

I am trying to adapt an existing code to a 64 bit machine. The main problem is that in one function, the previous coder uses a void* argument that is converted into suitable type in the function itself. A short example: void function(MESSAGE_ID id, void*...

I have seen a few (old) posts on the 'net about hacking together some support for pre-compiled headers in CMake. They all seem a bit all-over the place and everyone has their own way of doing it. What is the best way of doing it currently?

How does one do this? If I want to analyze how something is getting compiled, how would I get the emitted assembly code?

How do I list the symbols being exported from a .so file? If possible, I'd also like to know their source (e.g. if they are pulled in from a static library). I'm using gcc 4.0.2, if that makes a difference.

I am forking a number of processes and I want to measure how long it takes to complete the whole task, that is when all processes forked are completed. Please advise how to make the parent process wait until all child processes are terminated? I want to m...

What's the closest GCC equivalent to this MSVC preprocessor code? #pragma warning( push ) // Save the current warning state. #pragma warning( disable : 4723 ) // C4723: potential divide by 0 // Code which would generate warnin...

I want to make a simple, simple DLL which exports one or two functions, then try to call it from another program... Everywhere I've looked so far, is for complicated matters, different ways of linking things together, weird problems that I haven't even be...

I have a C++ library that provides various classes for managing data. I have the source code for the library. I want to extend the C++ API to support C function calls so that the library can be used with C code and C++ code at the same time. I'm using ...

Why does this code: class A { public: explicit A(int x) {} }; class B: public A { }; int main(void) { B *b = new B(5); delete b; } Result in these errors: main.cpp: In function ‘int main()’: main.cpp:13: error: no matching func...

We have a new application that requires glibc 2.4 (from gcc 4.1). The machine we have runs on has gcc 3.4.6. We can not upgrade, and the application must be run on this machine. We installed gcc 4.1, however, when it comes to compile time it is using...

This is a second-hand question from an OS development site, but it made me curious since I couldn't find a decent explanation anywhere. When compiling and linking a free-standing C++ program using gcc, sometimes a linker error like this occurs: out/kern...

What is the difference between g++ and gcc? Which ones should be used for general c++ development?

C++ guarantees that variables in a compilation unit (.cpp file) are initialised in order of declaration. For number of compilation units this rule works for each one separately (I mean static variables outside of classes). But, the order of initializatio...

So I am a new programmer and I just installed XCode on my Macbook to get the GCC. I think Xcode is the only way for getting GCC on OSX. Now when I run my Hello World application, in C++, g++ comes up saying it is version 4.0.1 but when I look for commands...

I get this message when compiling C++ on gcc 4.3 error: ‘NULL’ was not declared in this scope It appears and disappears and I don't know why. Why? Thanks.
